With the rapid development of smart phones, mobile phone protective film and other accessories are also popular among customers! Mobile phone protective film can be divided into mobile phone anti-spy film, mobile phone anti-blue film, mobile phone hydraulic film, mobile phone explosion-proof film according to the purpose. Wait. Then the mobile phone protective film can be divided into several according to the material?
1.9H nano glass screen protector
The surface layer of 9H nano film protective film is made of PET, 9H hard, which is three times that of ordinary protective film. The bottom layer is made of soft TPU polymer nano supramolecular material. It features 360-degree bending, 99.8% high-definition, shock-resistant, explosion-proof, shatter-resistant edges that are more durable than any tempered glass screen protector. It can be used for more than 12 months and lasts longer than any normal screen protector. Nano material can be anti-fouling, waterproof and anti-fingerprint, easy to clean!
2. Double layer PET protective film
The two layers of PET material are bonded together and the thickness is also thick enough to reach about 0.25mm. The lowest cost is it, the surface is blue PET release film (in other words, the explosion-proof film is now blue), this has no explosion-proof effect, purely flicker consumers, many manufacturers use the high-definition film of PET plastic before useless Finished, all thrown out, is this kind of junk goods, 99% of the market is now this kind of goods.
2.TPU+PET screen protector
The TPU is a real explosion-proof membrane, but the explosion-proof effect depends on the thickness of the TPU, so why some can lick the walnut, and some can be used as a hammer to nail, there is a difference. The thickness of TPU is generally 0.1mm/0.15mm/0.2mm. If the nail can be 0.2mm, the total thickness of a film should be about 0.35mm. Moreover, the TPU material is also good or bad. Not made in China. The cost of the entire material is four to five times that of the first one above, so know why 99% of the market is the first one?
3.PET+TPU+PET protective film
This cost is relatively higher, almost twice as high as the second. Three-layer composite explosion-proof membrane, TPU thickness is generally about 0.15mm, but there is a layer of PET on the surface of TPU, the surface can handle a variety of processes, such as scratch resistance can reach 5H, anti-fingerprint prevention, etc., it is not the second Can be compared. The effect of this explosion-proof membrane can also achieve the second effect.
4.PET+TPU screen protector
This kind of protective film is more difficult to produce, but it is better when it is filmed. Such protective films are generally used for export, and there are currently few manufacturers of such films in China. The new school is a screen protection film manufacturer with 10 years of manufacturing experience, which can produce screen protectors of various material types!
5.TPU protective film
This type of explosion-proof membrane, if the knife mold is properly opened, the material is sticky, and can be fully covered with a 2.5D screen. But one is not good, because this explosion-proof membrane is slightly sticky, the general consumption is not attached, it is easy to stick bad. However, this film is very thin, about 0.2mm overall, and now, many 2.5D screens will have the problem of smashing the edge of the tempered film. With this explosion-proof film, there is no such thing as broken edges.
6. Tempered glass protective film
Tempered glass/Reinforcedglass is a safety glass. The glass has very good wear characteristics and is very hard with a Vickers hardness of 622 to 701. Tempered glass is actually a kind of prestressed glass. In order to increase the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the resistance of the glass itself. Wind pressure, cold and heat, impact and so on.
